There are two main different AIT types: type 1 amiodarone-induced thyrotoxicosis (AIT1) is a form of iodine-induced hyperthyroidism, which develops when a thyroid with subtle functional autonomy is exposed to iodine excess contained in the amiodarone molecule; type 2 amiodarone-induced thyrotoxicosis (AIT2) is a destructive thyroiditis, which may develop even in a normal thyroid gland and is due to the leakage of preformed thyroid hormones from damaged thyroid follicles [2]. Here, TG is linked to thyrotoxicosis.
